Hi Craig, Cheers for the reply. I thought about drilling the bottom out as its about the only option however as it had ran OK up until recently I decided to re-assemble it as it was. I checked the adjustments as per the manual, well best as I could figure them out anyway and all seemed OK so I reinstalled the carb and soon as the fuel got through she fired up and ran smoothly and sounds great. Revs freely with no splutter or hesitation and the choke came right off correctly on warming up...
Haven't had chance for a road test with some load as yet as I have a slight weep from the filter bowl gasket to rectify first. If all is OK then I'm going to leave well alone. As you say fuel must be getting in somehow probably from the long slot in the side of the accelerator pump section...
Im getting a vac gauge this week to set up the idle mixtures as per the procedure I think previously posted by Owen. Will let you know if it runs OK...

Thanks, Dave.
